Hi, everybody:
I'm working on porting Linux to a MIPS based processor whose IP is from 
Lexra's LX4189 processor.

I started my work from the linux MIPS port of oss.sgi.com.  Right now 
the kernel can boot and run some user applications well.

But I met a problem that once a process raises any kind of signal, 
kernel will send a SIGILL signal to the process which let the process stop.

I traced the kernel source and found SIGILL is sent by the exception 
handler, do_ri().

The problem is very weird because when I change to another crosscompiler 
or insert some asserting code to functions in signal.c.  The kernel 
become unbootable.  I hope someone can give me directions to solve this 
bug or tell me who already done Linux on Lexra?


kernel version:2.4.17.
toolchain: GCC 3.1 from ftp.cotw.com.
use new IRQ and new timer interface.
